摘　　要：大庆油田北一区断东二、三类油层经过水驱阶段的开发,目前还存在大量剩余油.通过数值模拟计算,分析二、三类油层的合理开发次序及其由水驱转入化学驱阶段的合理时机.结果表明:二、三类油层同时开发的效果好于次序开发的效果;先开发三类油层好于先开发二类油层;对于某一类油层的驱油效果,先开发该类油层要好于二、三类油层同时开发的驱油效果;越早进行化学驱,油层最终采收率越高.At present,there is still a large number of residual oil after the water flooding stage in the second and third type reservoirs,which is at the east of the fault block in Beiyi district of Daqing oilfield.The proper development priorities and the reasonable time change from water flooding into chemical flooding stage for the second and third type reservoirs can be calculated through the numerical simulation.The results indicate that the effect of developing the second and third type reservoirs at the same time is better than that of the priority development.Developing the third type reservoir firstly is better than developing the second type reservoir first.As to the flooding effect of a certain type reservoir,developing this type of reservoirs firstly is better than developing the second and third type reservoirs at the same time.The sooner the chemical flooding goes,the higher the ultimate oil recovery is.
